Participants

Reaction Steps

Following the procedure as describe in Example 9, making variations as required to replace 2-(3-benzyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid with 4-methyl-2-(2-oxo-3-(4-(trifluoromethyl)benzyl)imidazolidin-1-yl)thiazole-5-carboxylic acid to react with 3-(aminomethyl)pyridine in place of benzylamine, the title compound was obtained as a white powder in 49% yield: mp 107-108° C.; 1H NMR (300 MHz, CDCl3) δ 8.56 (s, 1H), 8.44 (s, 1H), 7.66 (d, J=7.8 Hz, 1H), 7.56 (d, J=8.1 Hz, 2H), 7.35 (d, J=8.1 Hz, 2H), 7.23-7.19 (m, 1H), 5.59 (s, 1H), 4.55 (d, J=5.7 Hz, 2H), 4.47 (s, 2H), 4.04 (t, J=8.1 Hz, 2H), 3.43 (t, J=8.1 Hz, 2H), 2.55 (s, 3H); 13C NMR (75 MHz, CDCl3) δ 162.6, 157.2, 155.4, 153.5, 149.1, 148.6, 139.6, 135.8, 134.1, 130.5, 128.4, 125.8, 123.6, 122.1, 117.1, 47.5, 42.0, 41.8, 41.3, 17.2; MS (ES+) m/z 476.3 (M+1).
